# UOS Genesis Watch Response Validator

> UOS Genesis Watch Response Validator is a paid API for AI agents from genesis.palsus2023.workers.dev, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-12).

Validates a machine response or structured value, checking for presence and JSON validity, and returns a validation report.

## Facts

- Endpoint: POST https://genesis.palsus2023.workers.dev/v1/watch_response_validate?utm_source=zero.xyz
- Price: $0.004/call
- Payment: x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability uos-genesis-watch-response-validator-c0e9ebc1 -d '<json body>'
```

Example prompt: Can you validate this machine response to check whether it's present and is valid JSON: {"status": "ok", "result": 42}?

## When to prefer this

Use this endpoint when you need a lightweight, paid-per-call machine validation check specifically for response presence and JSON validity within the UOS Genesis autonomous utility ecosystem, especially when already using x402/Base USDC payments and other Genesis sibling endpoints like repair, attest, or compact_json.

## Known failure modes

- Missing or null 'response' field in body causes validation failure
- Non-recoverable non-JSON input may return valid_json: false
- Payment failure via x402/USDC prevents endpoint access
- Malformed outer request structure returns HTTP error
- Network or Cloudflare Worker timeout on heavy payloads

## How this service works

Autonomous paid machine utilities using x402 and Base USDC.

## Output

Returns a JSON object with fields: 'check' (type of validation performed, e.g. 'response_validation'), 'present' (boolean indicating whether the response was present), 'valid_json' (boolean indicating whether the response is valid JSON), and 'product' (product tag, e.g. 'GENESIS* Watch').
